Dr. Dongil ChoiMosaic 3D applies US patented 3D CCT technology to three-dimensionally disperse energies of various depths and intensities in a single shot. Compared to the flat irradiation of general fractional lasers, stimulation is delivered more evenly to areas with uneven depths, such as scar tissue.

Dr. Dongil ChoiBoth procedures are HIFU-based, but Shurink is a subsequent technology that reduces pain and maximizes effects. The key difference is that Ultherapy® uses DeepSEE™ visualization ultrasound to perform the procedure while directly viewing the SMAS layer. For a detailed comparison, Ultherapy pageplease refer to.

Dr. Dongil ChoiXERF combines two frequencies, 6.78MHz and 2MHz, to target the dermis and subcutaneous fat layers simultaneously. While conventional RF targets only the shallow dermis, XERF reaches a depth of 5~10mm.

Dr. Dongil ChoiYou can directly verify the genuine product through MERZ headquarters. We issue certificates corresponding to the number of genuine tip lines, and the number of shots on the certificate exactly matches the number of procedure shots.

Dr. Dongil ChoiIt is performed after topical anesthesia, and as a non-invasive method, pain and irritation are relatively low. There are individual differences, and details will be provided during consultation.

Dr. Dongil ChoiPain is reduced compared to existing lifting procedures, and the two-way procedure mode shortens the procedure time, lessening the burden. Numbing cream is applied before the procedure.

Dr. Dongil ChoiUltherapy and Shrink are ultrasound (HIFU)-based, while XERF is monopolar RF-based. The suitable procedure varies depending on skin thickness and the area of concern.

Dr. Dongil ChoiThere are individual differences, but anesthesia is not mandatory and is available upon request. Temporary pain may occur while 60~70℃ heat energy is delivered to the SMAS layer.

Dr. Dongil ChoiEpidermal damage is minimized, allowing for a quick return to daily life. Temporary erythema and micro-crusting may occur, and it stabilizes relatively quickly with proper moisturizing care.

Dr. Dongil ChoiDerma (1.5) / Eye (2.0) / Cell-up (3.0) / Line-up (4.5) cartridges are combined according to individual skin thickness and condition. Gangnam Seoyeon actively utilizes 3.0 and 4.5 cartridges for deep penetration.

Dr. Dongil ChoiThe ICD Cooling system controls skin temperature in real time to reduce pain. Anesthesia is not mandatory but is available upon request.

Dr. Dongil ChoiThe key difference is that Ultherapy® is performed while directly viewing the SMAS layer with DeepSEE™. Shurink is a HIFU-based non-surgical lifting, and XERF is based on monopolar RF high-frequency.

Dr. Dongil ChoiIt varies depending on the scar type and depth, but regular treatments of 3 to 5 sessions or more are usually recommended. The exact number of sessions will be custom-designed after diagnosis.

Dr. Dongil ChoiImmediate return to daily life is possible. There may be temporary mild swelling and erythema.

Dr. Dongil ChoiImmediate return to daily life is possible. Makeup is okay on the same day, and no separate recovery period is required.
